A 26-year-old mother of two young boys and several months pregnant with her third child was found stabbed to death inside her Sunset Park apartment. Police spent several hours talking to Yorceli Flores's 22-year-old boyfriend who made the grisly discovery that Flores had been stabbed several times in the chest at 4 a.m. yesterday. Flores had moved to Brooklyn from Mexico at age 16 and had an order of protection against her previous boyfriend that led to his deportation—he is the father of her two children. Police have recovered a knife at the murder scene, but no arrests have been made. A neighbor in the 58th Street building Flores had lived in told NY1, "She was stabbed and it's terrible because to live around here you don't know what to expect anymore. It's just terrible and it's sad because she was so young."
